877986 ÷ 88 
We want to divide 877986 by 88.

Moving on to step 1:
If we divide 8 by 88, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 88

Let's proceed to step 2:
88 goes into 87 0 times with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Fetch the next digit (7) from the dividend, attach it to 87 and continue: 877 / 88

Let's proceed to step 3:
88 can be fit into 877 9 times, resulting in a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 85 after subtracting 792 from 877.
Grab the next digit (9) from the dividend, add it to 85, then carry on: 859 / 88

Going ahead to step 4:
88 goes into 859 9 times with a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we subtract 792 from 859, we get 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 88

Moving on to step 5:
The number 88 fits into 678 7 times, leaving a remainder of 62.
Write down 7 as next digit of the result. 
Result so far: 997.0
If we take 616 away from 678, we end up with 62.
Take the next digit (6) from the dividend and append it to 62, then repeat: 626 / 88

Advancing to step 6:
88 goes into 626 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 9977.0
The remainder is 10 after subtracting 616 from 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 88, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 9977.1
If we subtract 88 from 100, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
If we divide 120 by 88, we get 1 and a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 9977.11
Subtract 88 from 120 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 9977.11 with a remainder of 0.032.
